Patent CA-2248036-A1 (CA)
Title: Puzzle holder
Inventor: RIOUX MARCEL
IPC: A63F9/10
Filed: 1997-02-03
Abstract: This jig-saw puzzle holder comprises two co-extensive work panels hinged together at their inner edges to take a closed folded position and an open coplanar position with their inner edges forming a smooth joint. A liner sheet covers and is secured to the panels and serves as a work surface upon which puzzle pieces can be assembled. To each panel is associated a generally co-extensive flexible cover sheet to cover puzzle pieces on the liner sheet. The liner and cover sheets are hook-and-loop fastener fabric so that the cover sheets can adhere to the liner sheet to surround the partially assembled puzzle pieces and thus prevent shifting of these pieces. When the pieces are being assembled, the cover sheet is rolled up and retained in an out-of-the-way position. Each panel is provided with a drawer to store individual puzzle pieces. Each panel is used to assemble half of the completed puzzle and the two halves are assembled across the smooth joint of the two open coplanar panels. A foldable support serves to maintain in a viewing position the picture of the completed puzzle on the cover of the puzzle container box.  Latches releasably retain the panels and drawers in closed position. The outer portions of the panels form a handle for conveniently carrying the folded holder.

Title: Combined cardiotomy fluid and venous blood reservoir
Inventor: MCBRIDE ROBERT R
IPC: A61M1/36
Filed: 1997-07-31
Abstract: A combined cardiotomy and venous blood reservoir (10) according to a preferred embodiment of the invention provides a separate in-flow path for both cardiotomy fluid and for venous blood, and includes a cardiotomy fluid filter element (66) also serving as an initial de-foamer. The cardiotomy fluid is de-foamed, filtered, and again de-foamed. The venous blood is de-foamed, and then both fluids are combined for flow from the reservoir (10). The filter area (152') provided for cardiotomy fluid is advantageously separated from the area of a final de-foamer element (152''). Thus, both the cardiotomy fluid and venous blood may flow through this final de-foamer element (152'') simultaneously along separate flow paths. The reservoir (10) design provides greater freedom in selecting adequate filter area (152') for the cardiotomy fluid, while allowing the selection of effective de-foamer element (152'') area in order to achieve acceptable flow rates for both cardiotomy fluid and for venous blood under various conditions of operation for the reservoir (10).  An advantageous ratio of filter (152') and de-foamer element (152'') areas to the volume of the reservoir (10) results, with the reservoir (10) requiring only an essential volume of fluid for processing. Also venous blood and cardiotomy fluid flow inlets (32, 34) to the apparatus may be rotatable in plan view independently both of one another and of a housing (12) of the reservoir (10).

Title: Document binder with cover pocket for custom title sheet
Inventor: ONG BON S
IPC: B29C65/08
Filed: 1999-03-16
Abstract: A document binder is formed with front and back covers hinged together in articulated fashion with a spine located therebetween. An overlay is provided across the outer surface of at least the front cover and the spine and is secured by fusion to inner and outer, plastic cover sheets that encapsulate a flat, stiff, front cover core, spine, and back cover core therebetween. A front cover title sheet pocket is defined between the overlay and the outer, plastic cover sheet. The title sheet pocket is of a narrow enough width to readily accommodate title sheets printed on paper of standard width, such as eight and a half inches.      The fabrication technique employed allows a title sheet pocket to be created for the front cover of the document binder which snugly confines the title sheet and prevents it from shifting laterally as occurs in conventional devices. The creation of title sheet pockets with this configuration is possible according to the method of the invention by first fusing together the overlay to the outer plastic cover sheet along a band of attachment near the demarcation between the front cover and the spine, and then fusing the overlay, outer cover sheet, and inner cover sheet together so as to encapsulate the nonfusible, flat, stiff core elements between the two cover sheets.      An inside pocket sheet may also be fused to the inner cover sheet during the same step of fusion so as to form pockets on the insides of the front and back covers.

Abstract: An apparatus and method for collecting liquid spillage at rail facilities including the plurality of center pans (10) and side pans (14) arranged in end to end relation. The pans (10, 14) are formed of a molded lightweight plastic material, preferably high density polyethylene. Each pan (10, 14) has a molded downward extending vertical drain pipe (54, 78) which fits within an elastomeric sleeve (60) about an upper drain opening (34) in a transverse drain conduit (28) positioned between a pair of crossties beneath the pans (10, 14). Each center pan (10) has a resilient upwardly inclined side flange or lip (44) which fits in sealing relation against adjacent rail (12) at the juncture of the head (16) and the vertical web (18) of the rail (12). For installation, the center pan (10) is preferably installed by first inserting one resilient side flange (44) beneath the head (16) of an adjacent rail (12) and then lowering the bottom (40) of the pan (10) onto the upper surface of the crossties (24) with drain pipe (54) received in sealing relation within the aligned elastomeric seal (60). Then, the opposed side flange (44) supported on the upper surface of the head (16) is forced or pushed downwardly beneath the head (16) where it snaps into sealing relation generally at the juncture of the vertical web (18) and the head (16) of the rail (12).

Abstract: A hearing aid circuit using an averaging detector (60) and a plurality of time constants (62) to produce a compression control signal (64) to control the gain of a compression amplifier (16) which compresses an input signal when the averaging detector signal exceeds a predetermined threshold. The compression control signal has an attack and release time. The release time of the compression control signal is proportional to the duration of time during which the averaging signal's amplitude exceeds the predetermined threshold level. The release has a variable recovery rate. The recovery rate being relatively fast during an initial portion of the release time and relatively slower during the remaining portion of the release time. The hearing aid circuit may also use a volume control (18) to adjust the gain of the signal produced by the compression amplifier (16) without adjusting the gain of the signal produced by a linear amplifier (14) to provide volume control for soft sounds independent of loud sounds.

Title: Bi-directional ballscrew no-back device
Inventor: ZEBROSKI HENRY A
IPC: F16H25/24
Filed: 1999-04-15
Abstract: A bi-directional no-back device for a ballscrew rotatable in opposite directions has a ballscrew flange with radial surfaces at opposite sides thereof to receive and transfer a bi-directional axial and torque load from an external source. First and second thrust plates are moveable axially of the ballscrew in a housing to transfer compressive loads exerted on the ballscrew in one direction and tensile loads exerted on the ballscrew in the other direction. This maintains a first set of skewed roller brake rings in tight frictional engagement with the ballscrew flange, a first ratchet wheel and the first thrust plate assembly or a second set of skewed roller brake rings in tight frictional engagement with the ballscrew flange, a second ratchet wheel and the second thrust plate assembly, depending on the direction of the external force applied to the ballscrew. First and second pawl assemblies are mounted on the housing and cooperate with the first and second ratchet wheels to permit freewheeling of the first ratchet wheel in a first direction and freewheeling of the second ratchet wheel in the opposite direction, for controlling the effective brake torque applied by multi-stage brakes.
